Static Electricity / Static Charge in simple terms?
/ Static Charge is simply described as an
imbalance of positive and negative charges i.e. created or generated due
to the friction between two insulating surfaces that accept or donates
Electrons from last valance shell.
How is Static
Electricity is developed primarily by induction, friction and
In any of this process, frictional heat is produced. It
is more than enough to accept or donate the Electrons from the last
valance shell of molecule.
factors are responsible for development of Static Electricity?
The material types determine the amount of Static
Electricity that gets developed. Even the polarity of
Static Electricity will keep on changing depending on
the two different types of material.
This means, if
is rubbed against Product B, then Product A will develop a
Positive Static Charge. However if Product A is rubbed against Product
different composition) Product A might develop Negative Static
generation is also dependant on the product texture. A rough or matty
finish of the surface Product will have more friction hence more
Static Electricity is developed.
Finer / glossier the surface, lesser the
friction comparatively and subsequently lesser the Static Electricity
also plays a vital role in development of Static Electricity. It is
observed that level of humidity is inversely proportional to the
development of Static Electricity
whenever humidity is higher (water being conductor of Electricity),
development of Static Electricity is comparatively
lower. Because of humidity (more than 60%) Static Electricity leaks out to the earth. As the atmosphere becomes more dryer,
the development of Static Electricity tends to be more.
change – whenever any metal or object’s
temperature increases due to
increased conductivity, Static Electricity decreases. If
the material has good insulative properties then Static Electricity will
remain for more time.
It may be found
out that when certain object is hot, it will not carry any Static Electricity, however when it cools down it will develop some
Static Charge. For example: Injection Molding Machine.
objects having different levels of Static Charge are kept together
over each other or near vicinity, a combination and accumulation of Static Electricity takes place resulting in very high
Static Charge. This is also referred as Combination or Battery Effect.
repetition of friction between two objects and consecutive release
will tend to develop Static Electricity.
Static Eliminator ?
Static Eliminator is an instrument that
eliminates the Static Electricity or Static Charge.
Any material or object
when holding Electrical Charge of either polarity, which remain with
material over a certain amount of time is said to have a Static Charge
i.e. the Electricity or Electrical Charges of either polarity on the
surface that cannot move from one point to another.
Types of Static Eliminator
1) Mainly used for Grounding the Static Electricity
from the surfaces.
However, many a time it is not possible to give
points on the insulating surface.
2) If accumulated Static Electricity is more than
the handling capacity and
Grounding is provided, then abrupt spark
gets generated. This is more
hazardous in the process.
3) Grounding method is effectively used for removing the Static Electricity
from the lightning to protect the
Active Static Eliminator :
Mainly, this type of Static Eliminator
works on corona principle. When high voltage is supplied to the
sharp edge in the near vicinity of earthing, then very low intensity
corona is developed. This break the air molecule, in the near
vicinity of edge, is broken in positive and negative charge
particles / Ions. Opposite charges combine to neutralise each other
and similar charges help making the atmosphere conducting.
Atomic Bombardment :
Many a time specific Gamma rays are bombarded on the surface to
eliminate the Static Electricity. However this is
very costly process.
of Anti Static Chemicals:
Particularly in Textile, Paper, Plastic Industries, they add some
Anti Static Chemicals in raw materials before final processing. This
Chemical prevents the generation, accumulation of Static
Electricity. However, this hampers the product quality, as well as,
Accessories of Static Eliminator
Static Eliminator consists of mainly,
1) Drive Unit and 2) Ioniser
Drive Unit :
This is High Voltage Generator. Depending on Circuit Designer high
voltage value varies however it is just above the adequate voltage
required to break the air molecules in positive and negative Ions.
This high voltage is required to give to the Ionisers of different
shapes suitable for different Applications.
1) Channel type Ionisers are used in straight Film Wrapping
In this Wrapping process Film is cut and falls freely
overwraps the cartoon. However, due to Static
Electricity this cut Film
piece sticks to Rubber Roller or come out of the
Rollers. To avoid this
Channel type Ioniser is used in between Rollers and
2) Pipe type Ionisers are used in Textile, Rubber, Adhesive
Film, Printing, Laminations manufacturing Units /
Machines. Being the
width of the substrate is comparatively high
[more than 500 mm] Pipe
type Ionisers are quite useful due to its
3) Ring type Ionisers are specially manufactured for Form Fill
Machines where the Plastic Tube in which the
material is filled is
surrounded by this eliminates
4) Blower type Ionisers is used where ordinary hand cannot be
viz. to eliminate Static Electricity from
inner line of the Plastic Pipe.
Applications of Static Eliminator
Wrapping Machines -
Using Static Eliminator, the flow of Plastic Film cuts is properly
Form Fill Seal Machines
[FFS] - After filling the powders in the Plastic Tubes, some
particles get trapped in the seal. That developes pin holes in the
Packet resulting powder leakage. After using the Ring type Ionisers
the process is smoother.
a) In the BOPP wrapping process
b) Due to the fast continuous friction between Master roll and body
Container where it moves, heavy Static
Electricity gets generated and
developes abrupt sparks resulting the
pin holes in the Master roll using
the Static Eliminator lots of funds can
Adhesive Tapes / Printing
/ Laminating Industry - In the last Roll, heavy Static
generated that give heavy shocks to the Operators. Hence they
hesitate to align the Web keeping the wrinkles as it is. Moreover,
many a time it is a cause of fire hazard. Using the Pipe type
Ionisers you can get rid of all such problems.
Plastic Film Extruder
- using Pipe type Ionisers, shock, fire hazard, attraction of very
fine dust, is prevented.
a) Strainter Machine - use of Static Eliminator prevents the
pin holes in
the fabric, attraction of fine dust and shocks to the
b) Warping & Sizing Machines - use of Static Eliminator
sticking of yarns to each other.
Rubber Industries -
Heavy Static Electricity is generated on the Rubber Sheets that detoriates the
Product quality. Using the Static Eliminators,
Static Electricity is eliminated which helps maintaining the Product
quality and prevent the Operators from getting the heavy shocks.
Plastic Film Slitters
- As the Cutter moves very fast, it developes heavy friction with
the Film resulting the heavy Static Electricity
generation. Hence the Film cuts cannot get properly pilled up. Using the
Static Eliminator this process is smoother and faster without any

object can either have an excessive Positive or Negative Charge, you
need to deploy the methods to remove those individual Charges.
You can neutralize excessive
Static Charge by counter
acting Negative Static Charge through supply of Electrons.
You can neutralize
Static Charge by connecting it to

confine our discussion to elimination of Static
Electricity by the way of ionization viz. Passive ionization and High
Voltage Active Electrical Ionization using corona principle.
Static Eliminator works ?
Static Eliminator are working on corona principle, which are used for removing Static Electricity.
Static Eliminator protect valuable Electronic equipments, protect
from Static shocks, and fire Hazards occurring due to
Static Eliminator, a high voltage (upto 5 KVA) is supplied to sharp edged
pins. An air molecule in the vicinity of sharp edge are broken in
positive and negatively charged particles called as Ions. These ions
help neutralizing Static Electricity from the substrate. These are
called as Active Static Eliminator, which eliminate the Static
Electricity from the surface temporarily till another friction takes
